Andrew Costello said his job as Rutland’s city attorney is the best job he’s had “so far.”

Family, however, is pulling him away from the position at the end of the month.

“My wife’s home is in Lynbrook, Long Island, which is right next to Queens, N.Y.,” he said.

Costello, 36, said he was still looking for a job in the area. While there are plenty of positions open, he said there seemed to be just as much of a surplus of applicants.

“It would be an understatement to say he’s irreplaceable,” Mayor Christopher Louras said. “There’s no one that can fill his shoes. He’s talked me off the ledge a number of times and has been extremely, extremely successful in protecting the interests of the city in litigation and negotiations.”

Beyond that, Louras said he expected Costello would be missed by the community at large.

“He’s a young, bright hard-charger who has been involved,” Louras said. “He’s going to be more missed outside City Hall than he is in.”

A successor has been identified and will be named by the Board of Aldermen on Monday along with the rest of the mayoral appointments.

Costello took the job in 2007. Prior to that, he had been a deputy state’s attorney in Bennington County and worked in private practice in Brooklyn. As city attorney, Costello said, he appreciated the variety of work he got to undertake.

“Everything from union contracts to people who fall on the sidewalks,” he said. “You don’t get that level of variety in a lot of jobs.”

While leaving Rutland, his hometown, is bittersweet, Costello said he won’t stay away.

“My wife and I have agreed we want to raise our kids here, so I will return,” he said.
